VAPOR-'BURN ER.

SPECIFICATION forming part of Letters, Patent No. 455,966, dated July 14, 1891. Application filed November 6, 1890- -Serial No. 370,552. (No model.)

To all whom t may concern.-

Be it known that we, JOHN A. LANNERT and WILLIAM R. J EAvoNs, citizens of the United States, residing at Cleveland, in the county Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners; and we do hereby declare that the following is a'full, clear, and exact des'cription of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to vapor-burners, and is an improvement on a patent issued to William R. Jeavons, No. 438,548. In the said patent a burner is shown which is designed more especially to consume the lighter grades of hydrocarbons, such as gasoline and the like, although heavier oils may be burned therein with advantage.

The present invention is designed more especially to burn the heavier grades Yof hydrocarbons, such as kerosene or the like.

The invention therefore consists in the construction and combination of parts constituting the burner, substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is l a vertical central sectional elevation of the view of the same.

burner, showing the parts separated as for initial starting. Fig. 2 is a side elevation of the burner with the parts in position as when in use anda portion broken away in Section to show the relation of the bowl to the supply-pipe and its drip mechanism and shield. Fig. 3 is a front elevation of the locking-hanger adapted to support the operatinglever or arm. Fig. 4 is a cross-section of bowl, showing a modification of the inner groove for holding the wick. Fig. 5 is aplan Fig. 6 is another modification, showing a ledge for supporting the wick.

A represents the bowl which constitutes the lower portion of the diffusing or vaporizing chamber, and B is the upper portion, which, when the parts are brought togther, contitutes a cover for the outer. portion of the bowl A, -forming a chamber beneath the cover. A The plate B is designed to be stationary or fixed and might consti-tute a part of-v the top plate of a stove supported on legs, as usual.

The bowlA is movable within certain limits to and from the part B by means of a lever or arm O, hinged at one end on a fixed bar or strap D, and, extending across beneath the bowl, is bent upwardabout midway of its length, so that the bent portion will comeinto the opening in the center of the bowl and serve to support the bowl, and the opposite end of the lever is held by a notched hanger E. When the bowl is down, as shown in Fig. 1, for initial starting of the burner, the lever O rests on the notched extremity e, and when it is raised, as in Fig. 2, and the burner in operation the lever occupies the upper notch e. By thus lowering the burner-bowl it is made accessible to the operator, so that the oil therein may be conveniently ignited, whereupon the bowl is instantly restored to its raised position, as shown in Fig. 2. The said bowl is provided with a perforated tube F, arranged about its inner open space, thus forming an air-draft up through the center of the bowl, and the upper plate or cover B y has a perforated tube or chimney G so arranged that an open combustion-chamber is formed between said tubes when in working position, substantially as shown in the patent above referred to. A conical air and llame deilector H is shown as extending into the inside tube and resting, when said tube is down, on projections g, iixed to the outer tube. Vhen the inner tube is raised, the deflector H rests upon its upper end, the neck of the deiiector being slightly shouldered at 4h to form a seat for the end of the tube.

This arrangement always brings the tube and delector to their proper positions with relation to each other.

K represents an oil-supply pipe, which is fixed by suitable means to the 'stationary plate B. At the point of delivery of the supply-pipe is a drip-extension 1c or its equivalent, which leads from the end of the pipe below the plate B in such manner that when the bowl A is raised the oil willbe conducted into the outer groove or channel a of the burner below, and when the bowl is lowered it will conduct the oil into the. inner groove or channel ct', which contains the wick Il.

the bowl,'so that the inner'groove or channely a is thrown directly beneath the oil conveyer or conductor lc, and thus the oil is` caused to drop upon the wick Linto said inner channel; but when the parts are raised and the tube and bowl are in operating position the oil-conductor VJoccupies the relation to-the other parts seen in Figf2, wh'erethe oil is conveyed into the outer channel ct,-

which has no wick, and whichvv is partly or wholly overlapped by the projectingplate 13,'. thus forming a diffusing aswell as vapori,

ing chamber beneath said plate. p

Close to the dripextension k and extending from4 the upper portion of the supplylpipe is a shield c'or diverter, which serves to prevent any vapor that may be generated in the supply-pipe from entering directly into, the combustion-chamberand increasing'the` .flame at this point. This shield divertssuch vapor to the diffusing-chamber, thus contributing to produce an equal tlamejat'allpointgs.

whatever in the burner as a part :thereof when the burner is under headway and consumin g vapor instead of oil. Asbefore stated,

this burner is intended to use heavy hydro-v carbons, with which initial starting is not easily accomplished on a bare metallic'surface.

inner one being designed to be used with wick or its equivalent simply for initial startingand the outer one when the burner is un` der headway, in which case it serves both asy a vaporizing chamber and a distributing chamber to convey the vapor around to all,r sides of the burner, and thus secure a uni-` form flame at all points. I l

As here shown, the wick L lies upon the bottom of the channel d and when saturated with oil is lighted, and, burning from its`sur. face, heats the burner sufficiently to vapor-` ize the oil as it drips into the outergroove or.v

channel c. The oil inthe inner channel be-l ing consumed, vaporization goes on onlyin the outer one, and, in fact, mostly, if not wholly, at the point of supply, whence the va-.

por travels around `under the overhanging cover B to give an 'equal pressure and flow of' vapor all around the burner. The-vapor ris-` ing between tubes F G is mixed with air en-I 'tering through said tubes and is consumedv yielding a beautiful blueiiame. f`

. If preferred, the bowl might have a single groove and the wick L be supported above. the bottom of the bowl, as in Fig. 4, in which. 'n n are projections which hold the wick above It can be promptly effected by burn ing the oil from a wick, and hence theytwov channels or grooves in the burner-bowl, thethe bottom of the bowl, so that vaporization may occur on the metallic surfaceof the bowl apart from the wick when the bowlis heated. Fig'. 5 shows the plan of the projections 'n n. Fig. 6 has one projection orledge fn, which extends the entire length of the channel. Upon this projection the wick L is placed. The wick is raised above and away from the inflowing oil when the burner is under head- 'way to allow the oil to be vaporized, as in the case of a double-grooved burner, directly from the heated metallic surface and distributed, as above set'forth Thus all carbon deposit will be left on the metallic surface, where it can be readily removed, and the wick is kept free therefrom and will last for an indefinite period.

If 'the oil were allowed to drop in drop by drop by reason of its rapid evaporization, it might cause the flame to pulsate or fluctuate. Toobviate vthis a conductor 7c is provided, as above described, from the mouth of the pipe downward. This conductor may be made of a strip extending from the pipe to the bowl -or several links of chain or'the like. Thus the oil is ,given a steady eveniiow into the bowl'and the pulsating tendency is avoided.

The vaporizing-bowl is free to be removed,`

and this makes it convenient to cleanse the same when carbon accumulations occur.

The deiiector H has guides h at its lower vextremity for the inner'combustion iiue or tube F,'which guides serve to hold the iiue in proper position when raised or lowered. These guides might be placed on the iiue itself to bear against the outer `iiue G; but that would more or less obstruct the combustio,nchamber.

The matter pertaining to the delector H land the deiiector, substantially as shown and described, in itself and its connections are not broadly claimed herein, but are so claimed in our application, Serial No. 368,177, filed October 15, 1890.

Having thus described the invention, what we claim as new, and desire to secure vby'LettersPatent, is v 1. In a vapor-burner, the vapori'zing-bowl provided with a wick, the supply-pipe, and a conveyer for the oil between the end of the pipe and the bowl, and the combustion -'tubes, substantially as described.
